Carnival Liberty and Carnival Paradise each scored 100 during its most recent United States Public Health (U.S.P.H.) in Miami and Tampa, respectively, marking the seventh time that a Carnival Cruise Lines ships has earned a perfect U.S.P.H. inspection score this year.

To earn a 100 score, cruise ships must receive perfect marks on all 44 items that comprise the U.S.P.H.’s comprehensive Vessel Sanitation Program checklist. The unannounced inspections, which are conducted twice a year and required for any cruise ship with an international itinerary calling at a U.S. port, evaluate vessels in a wide variety of areas, including adherence to proper food handling, preparation and storage procedures, and overall galley cleanliness. Ships’ potable water supplies used in spas and pools are evaluated, as well.
